Hi @Sham000007,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

Thank you for posting and for sharing the image. From the photo, the screen clearly shows a green crash screen with the message: Your device ran into a problem and needs to restart. Stop code: KERNEL_SECURITY_CHECK_FAILURE (0x139). After this crash, the notebook cannot boot and gets stuck while loading, which usually indicates a driver, memory, or system file corruption, often triggered during gaming.
 

Steps to try:

Step 1: Perform a Hard Reset

This clears temporary hardware states.

1. Power off the notebook
2. Disconnect the charger
3. If the battery is removable, remove it
4. Press and hold the Power button for 15 seconds
5. Reconnect the charger (leave the battery out if removable)
6. Power on the notebook

Step 2: Access Windows Recovery Environment (WinRE)

Since Windows does not load normally:

1. Turn the notebook ON
2. As soon as the HP logo appears, press and hold the Power button to force a shutdown
3. Repeat this 2–3 times
4. Windows will enter Preparing Automatic Repair
5. Select Advanced options

Step 3: Run Startup Repair

1. In Advanced options
2. Select Troubleshoot
3. Select Advanced options
4. Click Startup Repair
5. Choose your account and enter the password

This fixes boot‑related corruption.

Step 4: Boot into Safe Mode

If Startup Repair does not resolve the issue:

1. Go to Advanced options → Startup Settings
2. Click Restart
3. Press 4 or F4 for Safe Mode

If the system boots in Safe Mode, the issue is driver‑related.

Step 5: Uninstall Graphics and Recent Drivers (Very Important)

Gaming crashes with a green screen are commonly caused by GPU drivers.

1. In Safe Mode, right‑click Start
2. Open Device Manager
3. Expand Display adapters
4. Right‑click the graphics device → Uninstall device
5. Check and delete the driver software for this device
6. Restart the notebook

Windows will load a basic display driver.

I hope this helps.
